So I bought a front of the car for a swap, but the buyer or seller (before me) thought that it will be a good idea to cut the harness inside of the car, now I'm missing a connector (from inside of the car) to the engine harness (I have this one), can't find a schematic, and I don't want to connect them left and right because I'm scared that I will burn something important, in the connector there's a + that's supposed to go from the key to injectors and dispenser, along with other cables that I presume are + for engine sensors and more, any help would be nice, check the images attached, in the cut harness, there are some cables that have identical size and colours like the ones in the connector, thanks in advance
